Last July, I wrote about the registry pattern and some of its advantages. These advantages include the ability to access objects across different areas of your application, and the storage of objects for later retrieval.
Much of the debate in the comments focused on whether or not the registry pattern was suitable for today’s object-oriented development, and some of the arguments focused on whether or not the “global scope” was a good place to have objects.
One of the biggest challenges in OOP programming with PHP is the ability to pass around objects and let other objects use them. This challenge can be solved with careful design, however. Here we will discuss the registry pattern, not a member of the GoF’s original patterns but still an important pattern nonetheless.
